I thought it may interst people to see what can be done with the tech nowdays.
I'm very interested, and thank you for sharing this. I looked at doing a 3D printed railroad locomotive in HO scale about a year ago. Between the learning curve for 3D modeling programs, and the limitations of the print media, I got bogged down and discouraged. Always a thrill to see success!
Good luck with your line of kits, although, seriously, in the Model Railroad "industry," resin kit manufacturers have never been a serious threat to the injected plastic industry. The resin builders have given us models we could never expect in injected plastic.
